Sustainability & Materials
“Each pair begins with organic cotton from GOTS-certified farms.”
To minimize environmental impact, we carefully select fibers that combine performance with responsibility. All yarns and dyeing processes comply with strict standards to reduce water consumption and chemical pollution.
• GOTS Certified Organic Cotton: Our cotton comes from GOTS-certified farms, ensuring sustainable and ethical growing practices.
• Reduced environmental impact: High-quality organic fibers, reduced water and energy use, grown without pesticides or toxic chemicals.
• Eco-packaging: Made from recycled paper and plastics — designed to minimize our footprint.
• Ethical local production: Manufactured in Portugal with fair working conditions and certified processes.
Quality Assured
• Each sock proudly carries the label Made in Portugal, a country renowned for its excellence in textile manufacturing. Production is carried out under the highest EU standards of safety, quality, and sustainability, providing an additional guarantee of trust and full traceability.
• We believe in complete transparency. That’s why we provide distributors and customers with a full technical sheet for every model, including details on materials, production processes, certifications and care instructions.
This allows for informed decisions and strengthens trust in our brand.

Material certifications:
Our socks are made with materials that carry internationally recognized certifications.
• OEKO-TEX® Standard 100: guarantees that every yarn and component of the sock is free from harmful substances to human health.

• Looking ahead: reforestation, recycling programs and new global partnerships for a greater impact.
Sport must move towards a more responsible future.
Timeline & Roadmap
Risks and challenges
Risks & Challenges We believe in full transparency — building something sustainable means facing a few challenges head-on. Here’s what we’re keeping an eye on and how we plan to manage them:
Sustainable Material Sourcing High-quality, eco-friendly yarns (like organic cotton and recycled fibers) aren’t always easy to source. We’re partnering with certified suppliers and have backup options in place to ensure consistency and quality.
Balancing Performance & Sustainability Sustainability shouldn’t mean compromise. We’re extensively testing our prototypes with athletes to make sure the socks perform just as well — or better — than non-sustainable options.
Production Costs Ethical manufacturing and premium materials do cost more, but we believe in fair pay and long-lasting quality. Your support helps us keep prices fair while staying true to our values. 
Manufacturing & Delivery Timelines Smaller sustainable production runs can take longer. We’ve built extra time into our schedule and will keep you updated every step of the way if anything changes.
Educating & Building Trust We know the market is full of “green” claims. That’s why we’re sharing our certifications, materials, and process transparently — so you can see exactly what makes our socks genuinely sustainable.
